In need of suspension help

I have a 2013 JKU sahara that i lifted myself with a 2.5" terra flex coil lift kit. I also added rims and tires at the same time. Tires are 315/70/r17 duratracs that measure to about 34".

My problem is that at highway speeds (100-120km/h), the jeeps steering seems loose and sometimes veers to one side or the other. Im just wondering if this is just to be expected with a lifted jeep or if something could be wrong.

By the way, i did have it aligned at fountain tire right after the lift and recently took it to an actual mechanic that i trust and he said everything looked good as well.

Looking good and actually being good are two different things. I assume the shop that aligned the vehicle provided you with a printout of the specs? Anything out of wack? If you didnt get a printout, and the shop cant pull up info from when they originally did the alignment, make them re-do it (for free... or at least at a discount) and provide a printout.

Generally speaking the TF lifts are really good and we don't usually hear many complaints.

Did you change shocks as well?

What tire pressure are you running?

Is it jumping around on bumps or ruts?

A copy of the alignment specs would be helpful.

I have 2.5" TF lift. Coil and Bilstein shocks. Same tires as you. Also have heavy front bumper and winch. It seemed like my jeep was drunk when I drove it. I changed the hardware and got a better track bar. Torqued everything periodically check make sure everything is tight. Rides like a dream now.

Thanks for all of the quick replies!
The tire pressure was originally at 50psi from fountain tire and after i dropped it to 30psi it still hasn't helped.
This is the printout after the first alignment. The guy said he could only adjust toe. The castor angle is out by a bit.. But how much is too much? My mechanic said it was close enough to not worry about.

And yes i changed the shocks as well to the upgraded bilsteins.
Its not jumping around in ruts at all, just pulls to one side or the other randomly on the flat sections of highway.
I could just be too picky maybe, but i would appreciate your guys' input.

That's odd usually the Teraflex lifts come complete with "everything you need ". Looks like the alignment results are showing otherwise.

Would you be able to recommend the parts to fix the castor problem? Im pretty decent working on vehicles but don't know much about suspension.

When you installed the lift, did you put it on the ground before you tightened and torqued everything?
